Cory Doctorow is podcasting his entire novel, Eastern Standard Tribe.
Boston’s excellent [Isabella Stewart Gardner Museum](http://www.gardnermuseum.org/) has a podcast of its classical music concerts. The sound quality is great, with occasionally too much background noise, and the performances sound good to my untrained ears. Highly recommended.
[This American Life](http://thislife.org/) finally has a [free podcast](http://biz.yahoo.com/prnews/061012/cgth054.html?.v=57). The archives are still locked up behind the Audible.com paywall but my commutes and workouts just got a lot more enjoyable.
The City of Boston has a podcast. I think it’s a little backward that Boston has a podcast before it has a blog, but kudos to the City for embracing new technology. I wonder if this is the first podcast produced by a city government.
